BUSHING REMOVEB AND REPLACER.

Application filed March 13, 1923. Serial No. 624,765.

To all whom it may comem:

Be it known that I, HIRAM E. GARDNER, Jr, a citizen of the UnitedStates, residing at Concord, in the county of Merrimack and State of NewHampshire, have invented certain new and useful Improvements in BushingRemovers and Replacers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The primary object of this invention is the provision of a tool for usein removing and replacing bushings of every description for wristpins,hangers and spring eyes and automobile parts requiring the replacementof worn bushings.

The invention has for a further object the provision of a tool wherebythe bushing may be removed or replaced without the necessity ofdelivering a blow thereon which tends to upset the end receiving theblow, thereby adding materially to the difiiculty of removing orreplacing the bushing.

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

. While the drawings illustrate an embodiment of the invention it is tobe understood that in adapting the same to meet different conditions andrequirements, various changes in the form, proportion and minor detailsof construction may be resorted to without departing from the nature ofthe invention.

Referring to the accompanying drawings forming a part of theapplication:

Figure 1 is a sectional viewillustrative of the invention,

Figure 2 is a plan view of'difierent sized collars, and

Figure 3 is a detail view in perspective of the tool.

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters.

The tool comprises a bolt or threaded member 1 having a head 2 at oneend and threaded in its length to receive a nut 3, whereby pressure isexerted to remove or replace the bushing. A collar is removably fittedon the bolt or member 1 and engages the head 2 thereof. This collarcomprises stepped portions 4 and 5, the part 4 being of larger diameterthan the part 5 and adapted to engage the end of the bushing 6, whereasthe part enters the bushing and snugly fits the opening thereof to braceand prevent spreading or crushing of the bushing when the pressure isexerted to remove or replace the same. These collars are provided indifierent sizes, as indicated most clearly in Figure 2, whereby to adaptthe tool for removing or replacing bushings of different sizes. Aspacing sleeve 7 is slipped upon the threaded portion of the member 1and engages the part 8 from which the bushin is to be removed or placedin position.

jam washer 9 is interposed between the nut 3 and the outer end of thespacing sleeve 7 the head 2 thereof, after which the member W is passedthrough the bushing with the part 5 of the collar entering the same andthe part 4 engaging the end of the bushing. The spacing sleeve 7 is nowplaced upon the threaded end of the member 1 and engages the part 8beyond the opening in which the bushing 6 is fitted. The jam washer 9 isnext placed in position, after which the nut 3 is' screwed upon theprojecting threaded end of the member ,1. As the nut 3 is 0 screwed upon:the member 1, the latter is moved in the opening of the part 8receiving the bushing 6, the latter beingwithdrawn and entering thespacing sleeve 7.

When replacing the bushing, the tool is ad- 1% justed so as to draw thebushing into the opening of the part adapted to receive the same. Inthis use of the tool, the spacing sleeve 7 may be dispensed with and thejam washer 9 arranged to engage the part 8 at $1M the end of the openingopposite that in which the bushing is introduced to be drawn into place.

What is claimed is:

1. A tool for removing and replacing m6 bushings, the same comprising athreaded member having a head at one end, a set 001 lar removably fittedupon the threaded member and engaging the head thereof which forms astop, the reduced part of the no collar being adapted to enter thebushing and the enlarged part to engage the end of the bushing, and anut threaded upon the member and adapted to exert a pressure to effectan endwise movement of the bushing.

2. A tool for removing and replacing bushings, the same comprising athreaded member having a head at one end, a set collar removably fittedupon the threaded member and engaging the head thereof which forms astop, the reduced part of the collar being adapted to enter the bushingand the enlarged part to engage the end of the bushing, a jam washerslipped upon the memberand a nut threaded upon the member and adapted toengage the jam Washer. 3. A tool for removing and replacing bushings.the same comprising a threaded member having a head at one end, a setcollar removably fitted upon the threaded member and engaging the headthereof which forms a stop, the reduced part of the collar being adaptedto enter the bushing and the enlarged part to engage the end of thebushing, a spacing sleeve slipped upon the member, a jam Washer engagingthe outer end of the sleeve, and a nut threaded upon the member andadapted to transmit pressure to the spacing sleeve through the jamWasher.

In testimony whereof I affix my signature in presence of two witneses.
